SPECIFICATION forming part of Letters Patent No. 717,928, dated January 6, 1903.

Application filed $eptember 24,1902. Serial No. 124,674- (No model.)

To wZZ whom, it may concern:

Be it known that I, BERT RIVKIN, a citizen of the United States, residing at New York city, in the county of New York and State of New Yorlghave invented certain new and useful Improvements in Oar-Gate-Operating Apparatus, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide improved means for opening the gates of elevated cars; and with this and other objects in view the invention consists in an apparatus for the purpose specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the sepa view of an air-cylinder which I employ and shows other parts of the apparatus to which the air-cylinder is secured; Fig. 4, a side view of a part of the car and the platform thereof and shows a part of one of the gates and a part of the apparatus for operating the gates; Fig. 5, a longitudinal section of the air-cylinder which I employ; and Figs. 6 and 7 represent sectional details of the construction.

In the drawings forming part of this specification, Fig. 3 is on a larger scale than the other figures of the drawings, and in said drawings I have shown at a a part of the end of an elevated car which is provided with the usual door a and platform a which is formed in connection with the bottom a of the car, and to the bottom of said platform and transversely thereof is secured a thick plate a with which a part ofmy improved apparatus is connected.

Secured to the bottom of the plate a is a frame 1), comprising top members b and end members b and secured in the bottom of the end members 79 of the frame 17 is an air-cylinder 0, and the said end members b of the frame 1) are provided with outwardly-directed jaws b, in which is mounted a horizontal which is com municated an air-supply pipe 0 and-this pipe may be connected with an airtank located beneath the car and designed to contain air under pressure, or the pipes a may be connected with an air-tank on the engine of a train which will supply air thereto and to the gate-operating devices of all the cars of a train in the manner of an ordinary air -brake system. The frame b is provided centrally of one side thereof with a projecting member (2 to which is pivoted at b a lever d, oneend of which projects outwardly and is provided with a cross-head d? and the other end of which projects inwardly across the cylinder 0 and is provided with a spiral spring 01 which is secured to one end of the frame 01 at (1 andwith a rope or cable 01 which passes through an opening (i in one end of the frame I).

The cross-head d of the lever d supports two vertieallyarranged shafts 6, each of which is provided at its lower end with a rack-pinion e which is secured thereto, and in the operation of the apparatus, as hereinafter described, the rack-bar d operates in connection with the pinions e to turn the shafts 6. Connected with and wound on each of the shafts e, above the cross-head d of the lever 65, is a cord or cablef, and these cords or cables f are passed outwardly transversely of the bottom of the platform of the car and around pulleys f and connected at f with downwardly-directed arms f, secured to the gates f at f, and other cords or cables 9 are wound on the shafts e below the cross-head d of the lever d, and said cords or cables 9 are passed around pulleys g suspended be neath the platform of the car by means of hangers g and from the pulleys g the cords or cables 9 are passed around pulleys g supported beneath the platform of the car by IOU hangers g and from which said cords or cables g are passed around other pulleys g beneath the platform of the car and from which said cords or cables 9 are passed around pulleys g and connected with the arms f of the gates.

It will be understood that the gates f are collapsible gates or what is known as lazytong gates, and the side members 9 of said gates are stationary, while the side members 9 are adapted to move toward and from the stationary sides g As thus constructed it will be seen that when the shafts e are turned in one direction the gates will be open and when said shafts e are turned in the opposite direction the gates will be closed. Mounted at the end of the car is a vertically-arranged shaft 71, provided at the upper end with a handle h the lower end of which passes into the cook or valve 0 said coupling being a three-way cock or valve and the passages therethrough being controlled by the lower end of the shaft h, which operates as a valve for this purpose, this construction being the same as an ordinary three-way cock or valve and being clearly shown in Fig. 7.

The spring (1 normally operates to draw theend of the lever d with which it is connected in the direction of the arrow X in Fig. 8, and the cord or cable (1 is intended to pull said end of said lever in the opposite direction, and this cord or cable is passed around a pulley 2 suspended beneath the platform of the car, and another pulley it also suspended beneath the platform of the car, from which said cord or cable passes upwardly and is suspended from a hook 72/1 in the position shown in Fig. 1, and said cord or cable may also be suspended from another hook 11 if desired, and the shaft 72 and cord or cable d are both under the control of and adapted to be con trolled by the guard or gateman.

When the shaft his turned in one direction, the air will rush into the cylinder 0 at one end thereof through one of the pipes c and the piston 0 will be moved in one direction, and when the shaft his turned in the opposite direction the air will rush into the other end of the cylinder 0 and the piston 0 will be moved in the opposite direction. In the position of. the parts shown in Fig. 2 it will be apparent that the operation of the piston c as above described would result in opening and closing the right-hand gate f. When it is desired to operate the other gate, the gareman or guard detaches the cord or cable (1 from book 71. and suspends it from the hook 71. and in this position of the cord or cable 01 the spring d will draw the lever din the direction of the arrow X, and the cross-head d of said lever will be turned so that the pinion e which is out of connection with the rack-bar b in the position of the parts shown in Fig. 2, will be thrown into connection with said rack-bar, and in this position of the parts the left-hand gate f will be operated.

Various changes in and modifications of the construction hereinbefore described may be made without departing from the spirit of my invention or sacrificing its advantages, and I reserve the right of making all such alterations therein as far as come within the scope of the invention.

In practice in order to properly support the shafts e and to provide means whereby the cords or cablesf and g will operate properly I provide the cross-head d of the lever d with two journals or extended bearings 2 and the upper ends of said shafts are provided with a rigid drum 3 and the lower ends thereof with a rigid drum 4, and the cords or cables f and g are Wound, respectively, on these drums, this construction or the details thereof being clearly shown in Fig. 6.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for opening and closing the gates of a car, an air-cylinder supported beneath the platform of the car and provided with a piston having rods which pass out through the opposite ends thereof, means for operating said piston, a rack-bar supported adjacent to said piston the ends of which are connected with said rods, and devices in 0perative connection with said rack-bar and the gates of the car whereby the movement of the bar will open and close the gates, substantially as shown and described.

2. In an apparatus for opening and closing the gates of a car, a cylinder supported beneath the platform of the car and provided with rods which pass out through the opposite ends thereof, means for operating said piston, a rack-bar supported parallel with said cylinder and connected with said rods, a lever pivoted adjacent to said cylinder and adapted to swing in a horizontal plane, and shafts supported by said lever and provided with pinions adapted to operate in connection with said rack-bar, means for swinging said lever so as to alternately throw the pinions of said shafts into connection with said rack-bar and devices in operative connection with said shaft and with the gates of the car whereby either of said gates may be opened or closed, substantially as shown and described.

3. In an apparatus for opening and closing the gates of a car, an air-cylinder supported beneath the platform of the car and provided with a piston having rods which pass out through the opposite ends of said cylinder, means for supplying air under pressure to the opposite ends of said cylinder, a rack-bar supported parallel with said cylinder and connected with said rods, a lever supported transversely of said cylinder and adapted to swing in a horizontal plane, shafts supported by said lever and provided with pinions adapted to operate in connection with said rack-bar, and cords or cables wound on said shafts in opposite directions and in operative connection with the gates of the car, whereby the turning of said shafts by said rack-bar will open and closethe gates, substantially as shown and described.
